| Question | Answer |
|---|---|
| Adenosine Triphosphate (ATP) | is the most important biological molecule that provides chemical energy |
| Cellular Respiration | is the catabolic pathway in which organic molecules are broken down to release energy for use by the cell. |
| Energy | the ability to do work |
| Metabolism | are all of the reactions in a cell |
| Photosynthesis | is the anabolic pathway in which light energy from the Sun is converted to chemical energy for use but the cell. |
| Thermodynamics | is the study of the flow and transformation of energy in the universe |
| Calvin Cycle | the second phase of photosynthesis in which energy is stored in organic molecules such as glucose. |
| Granum | stacks formed by the thylakoids |
| NADP+ | the electron carrier that forms the energy-storage molecule NADPH |
| Pigment | light absorbing colored molecules found in the thylakoid membranes of chloroplasts. |
| Rubisco | an enzyme that converts the remaining ten G3P molecules into 5-carbon molecules called ribulose |
| Stroma | the fluid -filled space that is outside the grana. |
| Thylakoid | flattened saclike membranes that are arranged in stacks. |
| Aerobic | metabolic processes require oxygen |
| Aerobic Respiration | includes the Krebs cycle and electron transport and is an aerobic process |
| Anaerobic Process | do not require oxygen |
| Fermentation | occurs in the cytoplasm and regenerates the cell's supply of NAD+ while producing a small amount of ATP |
| Glycolysis | the process by which glucose is broken down in the cytoplasm |
| Krebs Cycle | is the series of reactions in which pyruvate is broken down into carbon dioxide |
